5. Install drainfield during dry weather and soil conditions; any soil smearing must be
eliminated by hand taking.
6. Install threaded clean-outs at the end of all laterals (cap must extend to within six inches

Install laterals to the manifold with the orifices at 12 o'clock,(do not glue), after pressure
test and Environmental Health Dept. approval,turn orifices down(6 o'clock)and glue
laterals to manifold. Orifice shields may be used with orifices in the 12 O'clock position
in lieu of turning the orifices down to the 6 o'clock position.
12. Filter fabric required over drain rock prior to back filling. If the drain rock extends above
naturalgrade,run the filter fabric at least 2 inches down the trench wall.
13.Encase all water lines within 10' of diainfreld and under any driveway/parking areas.
14.Divert all storm water runoff away from on-site sewage system.
15.No curtain drains allowed within 10' of the up-slope edge or 30' of the down-slope edge
of the drainfield and reserve area.
16.Have the septic tank and pump chamber pumped or inspected every 3 years minimum.
17.No vehicular traffic over drainfield area.
18.Inspect floats,clean filters,and test high water level alarm every 6-12 months as needed.
19. All materials and workmanship must meet County and State regulations.

22. All pressure systems with a pump chamber outlet higher than the drainfield must have an
anti-siphon valve or a 1/8"hole drilled in the discharge pipe above the pump to prevent
siphoning. Ensure anti-siphon hole sprays down/away from tank opening.
2.3 All transport lines under driveways or puking areas must be encased to prevent crushing.
